Wien bridge oscillator. Wien bridge oscillator is a type of phase shift oscillator which generates sinusoidal waves at the output. The Wien bridge oscillator was named after Max Karl Wien was based on the bridge circuit developed in the 1890s. It is one of the simplest oscillators known for its audio applications.

Oscillator circuit must satisfy the following two conditions known as Barkhausen conditions: 1. Magnitude of the loop gain (Av β) = 1, where, Av = Amplifier gain and β = Feedback gain. 2. Phase shift around the loop must be 360° or 0°. Wien bridge oscillator is an audio frequency sine wave oscillator of high stability and simplicity.

Circuit Diagram of Wein Bridge Oscillator. Wein Bridge Oscillator is a two-staged RC coupled amplifier circuit. It has a feedback loop with a series R 1 C 1 circuit, also known as a High-pass Filter circuit, connected to a parallel R 2 C 2 circuit, also known as a Low-pass Filter circuit. This connection forms a selective second-order frequency-dependent Band-pass filter.

The circuit diagram of Wein bridge oscillator is shown below: Since it is simple & stable, it most commonly used audio frequency oscillator. The phase angle criterion for oscillation is that the total phase shift around the circuit must be 0°. Total phase shift around circuit 0° can be occurs when bridge gets balanced, that is at resonance.
